To express:Thearea of the given isosceles right triangle as a function oflength of one of its equal side.

Answer to Problem 90AYU
Area can be expressed as
Explanation of Solution
Given information:
Length of one of the equal side is
Calculation:
Isosceles right triangle must have two equal sides.
The equal sides should be the base and height of the triangle.
As hypotenuse is the largest side of right triangle.
Now, consider a triangle as shown:
Now, area of a right triangle is half of the product of its base and height.
Let us consider the area function be
Therefore, the area can be expressed as shown:
Area can be expressed as
